  • Method and system for designing the color of a coating composition on an article
    Patent number: 7787142
    Abstract: A method of designing the appearance of an article having steps of creating a digital file of a design configuration for an article, representing the design configuration on a computer screen, selecting or creating a color for a coating composition to be applied to the article, generating color data for the created color, merging the color data with the digital file of the design configuration, and displaying on the computer screen an image of the article coated with the colored coating composition. Accurate calibration of the color of the article on a computer screen allows for production of coated articles based on the generated color data. The color data is further transmitted to a formulation computer that determines the formulation for a coating composition exhibiting the color data. Output from the formulation computer may be directly transmitted to a production facility for coating articles with the coating composition.

  • Exterior-durable multi-layer composite coating compositions
    Patent number: 6517940
    Abstract: A multi-layer composite coating composition is provided. The multi-layer composite coating composition includes an exterior-durable, organic solvent-borne base coating composition from which a durable base coating is deposited, and an aqueous top coating composition from which a top coating is deposited over at least a portion of the durable base coating. The multi-layer composite coating compositions are particularly useful as coatings for preformed, three-dimensional, multi-faced substrates employed in building construction, for example, the elongated extruded aluminum substrates used for window and door frames. Coated substrates are also provided.

  • Anodized aluminum having protective coating
    Patent number: 5439747
    Abstract: A coating composition and method for protecting anodized aluminum, and the coated product are disclosed, wherein the coating comprises a crosslinking agent; a film-forming resin selected from the group consisting of polyester polymers, thermosetting acrylic polymers, and mixtures thereof; and an epoxy silane. The combination provides exceptional adhesion of the coating to anodized surfaces as well as good hardness.
